Application filed June 16,1905. Serial No. 265,543,

To all whom it may concern.-

Be it known that 1, PETER A. MoRTENsEN, a citizen of the United States,residing at Sanford, in the county of Conejos and State of Colorado,have invented a new and useful \Yhistle, of which the following is aspecification.

This invention relates to musical instruments, and has for its principalobject to provide a simple form of wind instrument in the nature of awhistle which may be held in the mouth and is adapted for the playing ofdifferent tunes or for the sounding of a call or alarm.

A further object of the invention is to provide a musical instrument ofsimple construction which may be formed of a single piece of die-shapedsheet metal and of such construction that slight variations in tone maybe made by reversing the position of the instrument in the mouth.

With these and other objects in view, as will more fully hereinafterappear, the inven tion consists in certain novel features ofconstruction and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and particularly pointed outin the appended claims, it being understood that various changes in theform, proportions, size, and minor details of the structure may be madewithout departing from the spirit or sacrificing any of the ad vantagesof the invention.

In the accompanying drawings, Figure 1 is a vertical section of amusical instrument constructed in accordance with the invention. Fig. 2is a perspective view of the same. Fig. 3 is a plan view of theinstrument. Fig. 4 is a front elevation of the same.

Similarnumerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

The musical instrument forming the subject of the present invention ispreferably formed of a single piece of die-formed sheet metal that iscentrally bent to form upper and lower plates 10 and 11, the point ofjuncture of the two plates being slightly rounded and the platesgradually diverging toward the outer end to form a small trumpet 12.That portion of the two plates which is received within the mouth isprovided with rounded ends 13, so arranged that the widest portion ofthe two plates is of greater width than the width of the short curvedwall 14 that connects them, thus leaving air-inlet orifices at theopposite ends of the mouthpiece. The metal beyond the mouthpiece is bentto form a trumpet, the opposite edges being turned or flanged andsecured to each other by solder or brazing.

In the upper and lower plates 10 and 11 are formed air-orifices 16 and17, that are of approximately equal area, but are disposed in differentvertical planes, the orifice 16 being nearer to the rear wall 14 thanthe orifice 17, and the instrument when in use is so arranged that theorifice 16 is uppermost. The air-orifices are under the control of thetongue of the operator, and an air-current may be forced to either orboth of said orifices, as well as through the space between the oppositeends of the widened portions of the plates, air being compelled to passthrough the trumpet, owing to the fact that the lips are held in suchmanner as to prevent the passage of air except through the trumpet.

\Vith a device constructed in accordance with this invention it ispossible to play any tune or air, and the volume of sound is completelyunder the control of the operator, so that the device may be used as amusical instrument or for the purpose of sounding a call or alarm.

Having thus described the invention, what is claimed is 1. A musicalinstrument comprising a mouthpiece, and a trumpet of less width than themouthpiece, said mouthpiece being formed of upper and lower members eachprovided with an air-inlet opening.

2. A musical instrument comprising a mouthpiece, and a trumpet, thelatter being of less width than the mouthpiece, said mouthpiece beingformed of a pair of flanged plates united at their rear edges andarranged on slightly divergent lines, each plate being provided with anair-inlet opening.

8. A musical instrument comprising a sheet of metal bent to form amouthpiece, and a trumpet, the sides of the mouthpiece being open, andthe sides of the trumpet being closed.

4. A musical instrument comprising a mouthpiece closed at its rear endand open at its opposite sides, and a trumpet extending from themouthpiece and of less width than said mouthpiece.

5. A musical instrument comprising upper and lower divergent platesconnected at their rear ends, and the sides of the front portions of theplates being connected to form a trum et, the plates havingnon-registering air-in et openings.

6. A musical instrument comprising a flat Whistle having spaced top andbottom members connected to each other at one end and provided withsound-holes, and a trumpet substantially rectangular in cross-sectionextending integrally'from the outer end of the top and bottom members ofthe Whistle, the

trumpet increasing gradually in height from the Whistle outward.

7. A musical instrument comprising a flat Whistle open at. the sides andfront and provided in its top and bottom members with sound-holes, and atrumpet extending integrally from the outer ends of the top and bottommembers of the Whistle.

8. A musical instrument comprising a fiat Whistle having spaced top andbottom members connected to each other at one end, and provided withsound-holes, and a trumpet substantially rectangular in cross-sectioneX- tending integrally from the outer ends of the top and bottom membersof the Whistle.

In testimony that I claim the foregoing as my own I- have hereto afiiXedmy signature in the presence of two Witnesses.
